High Torque Slotted Band Standard Slotted Band Torro Solid Band (W1 and W4)Construction:Wide screw housing riverted to saddle (1) in 4 spots to ensure full engagement of the 8 threads (2)One piece extended band liner (3) provides isolation of the hose from the band slots, thus preventing extrusion and shear of the hose cover through the slotsWide 16 mm x 0.7 mm thick band with 17Nm recommended tightening torque (about double that of the standard clamp)8mm A/F slotted hex head

Construction:Material (W4) and size range stamped permanently on the band to minimise errorsOne piece Stainless Steel housing1/2 inch (12.7mm) wide band with low free torqueWide operating range for each size5/16” (8mm) A/F Hex Head screw

Construction:Assymmetric screw area ensures even distribution of forces and safe assemblyShort screw housing saddle provides even contact pressure and improved effi ciencyAssymetric extension to the housing prevents tilt of the housing when tightened Purpose built hex screw guides the emerging band end during tightening Smooth band interior (W1 clamps) or stamped interior (W4), both with rolled edges7mm A/F slotted hex head all sizes

Selection of the appropriate clampConsider the clamping diameter ie make sure the clamp fits on the • hose

Select the correct band width to match existing system parameters•

Choose an appropriate material in terms of required corrosion • resistance

Allow for possible thermal loads•

Allow for possible mechanical loads•

Take system pressure into account, but in the context of the overall • hose, clamp and spigot combination

Professional hose clamp installationFit the clamp in the middle of the joint•

Fit the clamp perpendicular to the joint•

Tighten the clamp as slowly as possible•

The recommended screwdriver speed is based on test results • and should be observed. Note that exceeding the recommended tightening torque will not result in a proportionately higher pull-off force and / or clamping force

Exceeding the test torque may cause permanent damage to the • clamp and to the system (eg failure of the clamp after re-assembly)

Retightening the connection once, 1-5 minutes after the first • assembly, may be useful (depending on a possible relaxation of the hose material)

Suitable assembly aids include water or a water / alcohol mixture. • Soap solutions, grease and similar lubricants are NOT recommended

The assembly tool should be applied to the clamp in a perpendicular • manner

A hexagon screwdriver, flat wrench or special assembly tool provides • the safest tightening method (See IHC-DRIVER above)

TERMINOLOGY USEDThe tightening torque describes the recommended torque that is applied in order to tighten a hose clamp. It is largely defi ned in the DIN 3017 Standard and is measured by means of a torque wrench. However, better clamp designs incorporate design features that best convert the tightening torque into band tension, and so increase the tightness of a joint. Measurement of band tension (which is not covered in the Standard) provides the best objective measurement of clamping performance.

Pirtek clamping systems are manufactured in Germany by Norma®, who routinely conduct band tension measurements as part of their design and manufacturing processes.Fracture torque indicates what tightening torque will result in destruction of a clamp, and provides a guide to the overall robustness of a clamp. Field servicing of mobile equipment in the absence of torque wrenches often results in manually applied tightening torques that exceed recommended tightening torques.

Quoted test torques are generally 30% above recommended tightening torques, and represent the maximum value at which no permanent damage to a clamp will occur through over-tightening.No-load torque defi nes the torque needed to turn the screw without generating any clamping force. Low no-load torques with negligible deviations typify clamps that will perform well during assembly.

ASSEMBLY INSTRUCTIONS

Apply the pincers to one ear (either as pictured above, or 1. from the side using a side pincer tool), and close the tool with sufficient force to draw the lower radii to a 3/4 closed position. Repeat the procedure on the second ear, this time closing 2. until obvious hose compression is evident.Pinch the first ear a second time until both clamp ears 3. appear to be sharing the compression load equally as evidenced by symmetrical ‘Ω’ shaped formations.

IHCBSINSTALLATION PROCEDURE CONTINUOUS BAND

Slide the buckle onto the band with the ears pointing towards the end of the band. Form the loop of the clamp, holding band on band as illustrated, then slide the band end again through the buckle slot, bending the end approximately 25 mm under the buckle to hook it on the buckle.

For heavy duty jobs, double wrap the band

Place the band in the tool (IHCB-TOOL), push down on the gripper with the thumb, and tension the band strap by turning the handle. Maximum tension is achieved when the band stops moving through the buckle.At this point, roll the tool over the buckle. It will be necessary to reverse the tensioning handle approximately 1/2 turn as you roll the tool over to avoid band breakage. Judicious release of the handle will prevent loss of band tension during the roll over process.

Pull on the cutting lever to cut the band off at the correct length

Carefully hold the severedstub with the thumb andhammer the band flat overthe bridge of the buckle. Complete the clamp by hammering the ears overthe band

IHCPFINSTALLATION PROCEDURE PREFORMED CLAMPS

Place the Continuous Band Tool IHCB-TOOL in a vice and attach the Preform Adaptor IHCBF-ADP to the nose of the tool. Slip a Preformed Clamp into the tool and grip the tail end of the clamp with the eccentric lever of the main tool.

Insert the hose into the clamp and apply tension by turning the handle of the main tool. Hold the thumb on the side of the buckle where the band enters the jaws of the tool to assist in controlling the tension.Maximum tension has been achieved when the band stops moving through the buckle. At this point, roll the hose over until the shear hook engages behind the buckle edge. It will be necessary to reverse the tensioning handle approximately 1/4 to 1/2 turn (depending on hose diameter) as you roll the hose over to avoid band breakage. Judicious release of the handle will prevent loss of band tension during the roll over process.

(a) Pull on the cutter lever to cut the band

(b) Turn the disc by hand until tight. Use a ratchet spanner on the hex nut and operate it until the band shears

The completed PreformedBand assembly requires

no hammering or crimping

PIPE COUPLINGSNORMACONNECT®

Description: Types and Sizes: Applications:The NORMACONNECT• ® pipe coupling is a reliable connecting element for thick- and thinwalled pipesconforms to the latest DIN standard 86128• Sealing reliability is also ensured under the • condition of angular defl ection, slight pipe misalignment and even gaps between pipe ends of up to 35 mm (refer Pirtek)Pressure surges, vibration and structure-born • noise are absorbed to a considerable extentThe pipe coupling is of light weight, compact and • can easily be fi tted even in a confi ned space

Types:• Available in several types to cater for differing pipe materials and strain loadings (see table)Sizes:• Couplings are available to cover a range of pipe diameters from 26.9mm to 1200mm Larger capacities to 2032mm and 70 bar pressure subject to conditions

Feed and return lines for liquids, gas and • solids in industrial applications, shipbuilding, construction, fresh water supply, waste water treatment etc. – are joined quickly, easily and safely with these couplingsAn economical alternative to conventional pipe • joining techniques for nearly all kind of pipe material. All plain-ended pipes can be joined in a very short period of time without welding. The ready-to-fi t coupling is pushed over the pipe ends, aligned and rotated to any radial fi tting position. Tightening the two bolts alternately with a torque wrench is all it takes for a safe fi tting

Because of the complexities and scope of the possible applications for these couplings, Pirtek do not carry them as part of their normal stock range. Pirtek can nevertheless offer a full design and installation service covering all aspects of their usage. Please consult your nearest Pirtek Service Centre
